Technically, I think the GPS has a margin of error, that is, you can be some distance from the road on which it thinks you're traveling and it'll still give you credit for being on the right track. Certainly being in the other lane would qualify. For example, one of the eastbound highways near me is under construction, and as a result, they divert one lane of traffic onto one lane of the westbound lanes.My GPS doesn't think I'm in the wrong lane, it still thinks I'm over on the other side of the median, a good 50-70 feet away.

So I can see how this can happen with the GPS.

What I can't see is someone being so stupid as to not notice the oncoming traffic screaming past. Yes, it's possible that the GPS would not notice, but this fellow is clearly too dumb to drive. Too bad Darwin didn't fix the situation for us...

That was my thought. I've had a GPS try to turn me the wrong way down a one-way street. Seems like a great way for shady municipalities to rake in some cash. Figure out which roads are most popular with GPS routing and change them to one-way streets.

I've had this happen to me once, in downtown Honolulu, GPS turned me on to a street that was a bus/emergency vehicle only street. Had there been signage on the street I turned from, instead signage you could only see when you'd already made the turn, I wouldn't have turned, because I actually do look at the signs and such for one ways, etc when using a GPS.
